Title: Treatment for dust
Inventor: GOTOU KAZUYUKI
IPC: B09B3/00
Filed: 1981-08-17
Abstract: PURPOSE:To facilitate effective regeneration of molten slag by treating the dust produced from an incinerator for waste in a melting furnace of a direct conduction system and dividing the molten slag produced by the treatment to the molten slag in the upper layer consisting essentially of water soluble components and the molten slag in the lower layer consisting essentially of components hardly soluble in water. CONSTITUTION:The dust produced in an incinerator for waste is charged through a feed port 2 into the furnace body, where the dust is melted by heating with the gas injected through a nozzle 4 for injection of fuel gas for initial melting, whereby molten slag 9 is formed. The upper layer part of the formed slag 9 is discharged through a discharge port 6 which is provided in the higher position out of the two discharge ports provided to the furnace body. Said slag is released into a pit filled with water. Then, salts such as NaCl, KCl and others which are essential components are dissolved in the water. The lower layer part consisting essentially of components hardly soluble in water such as CaO, Al2O3 and the like of the slag 9 is discharged through the discharge port 7 provided in the lower position of the furnace body, and is carried and solidified together with heavy metals made unharmful.

Title: Flip chip bonding method
Inventor: UMEDA OSAMU
IPC: H01L21/60
Filed: 1992-05-21
Abstract: PURPOSE:To enhance accuracy of adhesive applying position by a method wherein a groove of predetermined width is made at a joint of bump and subsequently filled with conductive adhesive by means of squeegee or the like. CONSTITUTION:Resist 3 is applied uniformly by predetermined thickness in the flip chip mounting area on the top surface of a circuit board 1. The resist 3 is then removed from the joint of bump thus forming a groove 4 or predetermined width. The groove 4 is subsequently filled with conductive adhesive 5 by mans of a squeegee or the like and aligned. Bumps 7 formed directly on an IC chip 6 or the like are then positioned at the grooves 4 filled with the adhesive 5. The adhesive 5 is cured subsequently under specified conditions thus connecting the circuit board 1 and the IC chip 6 electrically. Remaining resist is then entirely removed and resin coating is applied thereon.

Title: Resistance welding machine
Inventor: SATOU RIYOUDA
IPC: B23K11/24
Filed: 1980-09-16
Abstract: PURPOSE: To provide a resistance welding machine of good rise characteristics of welding current by connecting the primary side of one of welding transformers to an AC-DC power source, and connecting the primary side of the other welding transformer to an AC power source via a bidirectional SCR at the polarity reversed from that of the primary side of the former transformer.  
     CONSTITUTION: While not in welding, the operator is simply required to turn thyristors 19, 20 off. Namely, voltage is induced on the secondary side of a welding transformer 10 but since the primary side of a welding transformer 11 is open, no voltage is induced in the secondary side. Moreover, the impedance viewed from the secondary side of the transformer 11 is extremely high and no welding current flows and no welding is carried out. On the other hand, at the welding, the operator turns the thyristors 19, 20 on. Namely, voltage is induced both in the secondary sides of the transformers 10, 11, and since they are connected to an AC power source 18 at the polarity reversed from the primary side of the transformer 11, the secondary side voltages of the transformers 10, 11 are added and this added voltage is applied to electrodes 14, 15, whereby the welding of objects 16, 17 to be welded is accomplished.

Title: Steering controller for autonomously traveling vehicle
Inventor: HATTORI AKIRA
IPC: G06T1/00
Filed: 1991-05-31
Abstract: PURPOSE:To smoothly travel a traveling route including a curve route with arbitrary curvature. CONSTITUTION:White line information consisting of a distance (x) to a white line 3 and a tangent angle alpha is detected based on an image in front of a vehicle 1, which is image-picked up by a video camera 2. Plural reference curvature radii R are previously set, and the reliability of the respective reference curvature radii R to a measured curvature radius (r) is calculated by a fuzzy operation. The regression function expression of the operation of a steering angle in the plural reference curvature radii R is previously provided. The steering angle theta(R) in the respective reference curvature radii is obtained by white line information by using the regression function expression, and reliability is weighting-calculated to the value of the steering angle theta(R). Thus, the value T of the steering angle fitted to the curvature radius of the curve of the traveling route is obtained.

Title: Production of roll for rolling
Inventor: SATO TETSUO
IPC: C21D8/00
Filed: 1980-09-19
Abstract: PURPOSE:To obtain a roll for rolling which is excellent in abrasion resistance, toughness and resistance to thermal cracking by a method wherein a cast article of a steel containing specified amounts of C, Cr, Mo, Ti, Si and Mn is hot forged in a specified temperature range. CONSTITUTION:The cast article of a steel containing, by weight, 1.5-3% of C, 2-13% of Cr, 0.2-1% of Mo, 0.1-1% of Ti, 0.2-1.5% of Si and 0.2-1.5% of Mn, the balance being Fe and unavoidable impurities, is hot forged in the temperature range of 1,100-900 deg.C. The hot forging is conducted in the above-specified temperature range because at a temperature of higher than 1,100 deg.C the forging is accompanied by violent oxidation which increase the amount of scale and makes it impossible to forge the cast article favorably, and on the other hand, at a temperature of lower than 900 deg.C the plastic deformability at the time of forging becomes poor.

Title: Weld joint
Inventor: MOCHIZUKI MASATO
IPC: B23K15/00
Filed: 1995-05-29
Abstract: PURPOSE: To enhance strength of a weld zone by fabricating with cladding by welding in multilayers smoothly with the use of a filler metal harder than the material to be welded, in welding a structural joint, and thereby relaxing a stress concentration in the weld zone. CONSTITUTION: The flange 3 and the web 4 of a structural tee weld joint are vertically joined by electron beam welding. After the completion of the electron beam welding, the shape of the weld root and toe of the tee joint is formed in a smooth curve, by smoothly cladding by multilayer welding and by means of a welding method other than electron beam welding such as submerged arc welding or shield metal arc welding 2, using a filler metal with a higher yield stress than the material to be welded, in order to make the weld zone of the tee joint to be such a joint shape as to avoid an angle formed by straight lines which is liable to cause stress concentration. Further, enhancement in strength is contrived through surface working, for example, by smoothly working by grinding.

Title: Sealing device for scroll compressor
Inventor: HAZAKI EIICHI
IPC: F04C23/02
Filed: 1981-08-21
Abstract: PURPOSE:To prevent seizure, by providing the tilting center portion of a shaft with a sealing means comprising an annular groove for keeping discharged gas from blowing through to an intermediate chamber and a spiral groove communicating with the annular groove, to cause oil film pressure on a bearing. CONSTITUTION:A shaft 9a tilts in an upper plain bearing 11 and a lower plain bearing 12. At that time, the clearance 38 between the sliding surface 37 of an annular groove 35 and a spiral groove 36 communicating with it and the shaft 9a opposite the loaded side is small. As the bearings 11, 12 wear with the lapse of time, the shaft 9a tilts and the clearance 38 opposite the loaded side is kept nearly equal to its original value corresponding to the unworn state of the bearings. For that reason, discharged gas is prevented from blowing through the clearance 38.
